Les Arts Florissants is a Baroque musical ensemble in residence at the Théâtre de Caen in Caen, France. The organization was founded by conductor William Christie in 1979. The ensemble derives its name from the 1685 opera Les Arts florissants by Marc-Antoine Charpentier. The organization consists of a chamber orchestra of period instruments and a small vocal ensemble. Current notable members include soprano Danielle de Niese and tenor Paul Agnew, who has served as assistant conductor since 2007. Jonathan Cohen is also on the conducting staff; Christie remains the organization's artistic director.
